Methods and apparatus to test electronic devices

摘要

Methods and apparatus to test electronic devices are disclosed. An example method includes setting a first controlled switch to prevent a current detect signal from tripping an overcurrent protection event controlling an operation of the device; setting a second controlled switch to route a first sensed voltage associated with the device to a voltage adjuster; sending a calibration current corresponding to a target threshold current through the device; detecting the first sensed voltage while the calibration current flows through the device; and setting a reference signal substantially equal to the first sensed voltage, wherein the reference signal is to be used to generate the current detect signal.
